Assertion (A) The aqueous solution of `CH_(3)COONa` is alkaline in nature.
Reason (R) Acetate ion undergoes atomic hydrolysis.

Options

A. Both (A) and (R) are true and (R) is the correct explanation of (A)
B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
C. (A) is true but (R) is not true
D. (A) is not true but (R) is true

Answer

A

Explanation

`CH_(3)COONa overset("Ionisation")underset("In aqueous solution")hArr underset("Strong base")(CH_(3)COO^(-)) +Na^(+)`
`CH_(3)COO^(-) +H_(2)O rarr CH_(3)COOH + OH^(-)`
Acetate ion undergoes anionic hydrolysis and the resulting solution is slightly basic due to excess of `OH^(-)` ions. Hence, both (A) and (R) are true and (R) is the correct explanation of (A).
